Which one of the following statements is incorrect about shunt capacit...
Incorrect Statement Explanation:
Shunt Capacitors:
- Shunt capacitors are used to improve power factor by supplying reactive power to the system.
- They are typically used for lagging power factor circuits to offset the inductive loads.
- The VAr (Reactive Volt-Ampere) produced by the shunt capacitors increases as the voltage drops, not drops as mentioned in the incorrect statement.
- Shunt capacitors help maintain the voltage value by supplying reactive power.
Variable Impedance Type Loads:
- Shunt capacitors are not of variable impedance type loads. They are fixed capacitors designed to provide a specific amount of reactive power to the system.
- Variable impedance type loads are typically used to minimize losses and voltage drop in a system, but shunt capacitors serve a different purpose.
Therefore, option 'D' is incorrect as shunt capacitors are not of variable impedance type loads.

Which one of the following statements is incorrect about shunt capacit...
Static Shunt Capacitor:
- The power factor can be improved by connecting capacitors in parallel with the equipment operating at a lagging power factor.
- It is always desired to commission a capacitor bank nearer to reactive load, this makes the transmission of reactive kVARr removed from a greater part of the network
- Shunt capacitors operate at leading pf (like No-load over-excited synchronous motors)i.e. they consume leading VARs by delivering the lagging VARs.
- Reactive power supplied by capacitor bank is given by the formula:
Advantages:
(i) They have low losses.
(ii) They require little maintenance as there are no rotating parts.
(iii) They can be easily installed as they are light and require no foundation.
(iv) They can work under ordinary atmospheric conditions.
(i) They have low losses.
(ii) They require little maintenance as there are no rotating parts.
(iii) They can be easily installed as they are light and require no foundation.
(iv) They can work under ordinary atmospheric conditions.
Disadvantages:
(i) They have short service life ranging from 8 to 10 years.
(ii) They are easily damaged if the voltage exceeds the rated value.
(iii) Once the capacitors are damaged, their repair is uneconomical
